Only after using sudo python ./awslogs-agent-setup.py --region us-east-1
on my Amazon Linux AMI, I found this tidbyte of Caution from AWS docs:
Do not update the CloudWatch Logs agent using the RPM installation method if you previously used the Python script to install the agent. Doing so may cause configuration issues that prevent the CloudWatch Logs agent from sending your logs to CloudWatch.
Now, how can I uninstall the python version to use the RPM installation?
